问题 Scientists hope the collision will produce a large crater in the comet’s surface in order to reveal the core and give some______to the origin of the solar system.

选项 A、sources
B、interpretations
C、clues
D、observations

答案C

解析 同定搭配。sources“来源,出处”,一般与of搭配;interpretations“解释,说明,翻译”,也是与of搭配;clues是“线索,暗示”,与to搭配;observations(复数)是“观察资料,(观察后的)意见”。从搭配和含义上都应该选Clues。故答案为C。
